SLEIGH-KNEE.

SPECIFICATION forming part of Letters Patent No. 382,397, dated May 8,1888.

Application filed November 25, 1887. Serial No. 256,118; (No model.) A

To all whom it may concern.-

Be it known that we, HERMAN WESLE and HENRY WESLE, both of Medford, inthe county of Taylor and State of Wisconsin, have invented new anduseful Improvements in Sleigh- Knees, of which the following is aspecification, referencebeing had to the annexed drawings, forming apart thereof, in which- Figure l is a perspective view of part of asleigh embodying our invention. Fig. 2 is a side elevation of the same.Fig. 3 is a longi tudinal section taken lengthwise of the runner, andFig. 4 is a detail perspective view of the joint of the sleigh-knee.

Similar letters of reference indicate corresponding parts in all theviews.

The object of our invention is to provide a sleigh-knee which will admitof asmall amount of motion in the runner to allow the runner to conformto the inequalities of thesurface over which it passes.

Our invention consists in the combination, with the runner and the beam,of a cylindrically-convex casting secured to the beam, bearing-platessecured to opposite sides of the runner, and hooks inserted in recessesin the bearing-plates and received in recesses in the convex plate, allas hereinafter more fully described.

To the runner A is secured a standard, B, having a concave uppersurface, 0, adapted to 'receive the cylindrically-convex plate D, se-

cured to the under surface of the beam E. The plate D is provided with acentral transverse slot, (1, with recesses b near opposite ends,withperforations extending through the plate at the inner ends of therecesses, and with semicircular groovesc near opposite ends forreceiving the fastening-clips F, by which the plate D is secured to thebeam E, the said fast: ening clips extending upwardly through the beamand receiving nuts d.

To the sides of the runner A and of the standard B are secured plates G,which are recessed on their inner faces for receiving the shanksof thehooks e, the said hooks extending through the plate D and into therecesses b. To retain the hooks e in their placesin the plates G therecesses in the plates are flared at their lower ends and beveled headsare v formed upon the shanks of the hooks e, which fit the flaredportions of the recesses.

A bolt, H, extends upwardly through the runner and through the standardB, and is passed through the slot at of the plate D and through a slotin the beam E. A transverse channel, f, is formed in the beam Eabove thestandard B, for receiving a fiat brace, I, which is attached to therunner A on opposite'sides of the standard B, and is provided withacentral slot, g, for receiving the upper end of the bolt H. The bottomof the channel f is made convex to allow of the necessary amount ofmotion in the runner A and brace I. As the runner passes over an unevensurface, the standard B and the plates G swing on the convex surface ofthe plate D.

The recesses 12 are closed at their outer ends to prevent the entranceof snow or ice.

Having thusfullydescribedourinvention,we claim as new and desire tosecure by Letters Patent- 1. As an improved article of manufacture, anattachment for sleigh knees, formed of the convex plate D, havingrecesses b and a central aperture, a, the recessed plates G, fitted tothe convex surface of the plate D, and the hooks 6, received in therecesses, substantially as specified.

2. In a sleigh-knee, the combination of the runner A, the standard B,the convex plate D, provided with the recesses 12 and central slot, a,the recessed plates G, the hooks e, the bolt H, and the brace I,substantially as specified.
